YouTube app audio is not in sync with Roku Streambar Se

Hi, Oxceranoid.

We understand that you're encountering audio issues with your Roku Streambar SE on YouTube, with audio that is not in sync. Rest assured that we'll help you provide a workaround to see if that resolves the problem. 

If the sound from your Roku Streambar does not match the picture on your TV, you may have encountered an audio/video synchronization error, or A/V sync error. One common sign of this issue is when you notice an actor's lip movements not matching the words they are speaking on screen. This type of A/V sync error is often referred to more precisely as a lip-sync error.

To troubleshoot this problem, try doing the troubleshooting steps below and let us know if that works for you: 

1. Are all titles on a channel or device affected?
   When you encounter an A/V sync error, stop the playback of the movie or TV show and try a different title. Try another title on the same game console if you are playing a video game with an A/V sync error. If you determine that the sync error is isolated to a single title, the movie, TV show, or video game is likely poorly authored or damaged. Try watching the movie or TV show on another channel with streaming content or content from your cable/satellite provider. With physical media, try cleaning the disc or replacing it with an alternate copy.
   
   If the A/V sync error affects multiple titles, continue to the next step.

2. Are all devices affected?
   If multiple titles are affected, switch your TV to a different device (from the one where the A/V sync error was discovered) and play a movie, TV show, or video game on the new device. If you discover that the sync error only occurs on the original device, try restarting that device.
   
   If the A/V sync error occurs with multiple titles on a single streaming channel, close the channel and try watching content on another streaming channel. If the A/V sync error disappears, re-launch the original streaming channel and resume playback of the duplicate titles to determine if the sync error was an isolated event. Contact the service provider to report the issue if multiple titles are still affected only on one streaming channel.
   
   If the A/V sync error affects all devices, continue to the next step.

3. Try adjusting TV settings.
   To help fix an A/V sync error, try adjusting the TV settings described below. For detailed instructions, consult the online documentation for your TV model or contact the manufacturer directly.
   
   
   • • Some TV models have an A/V Sync feature that can often be found in an Audio sub-menu within the Settings menu on your TV. If the feature exists on your TV, try adjusting it to see if A/V sync improves. The feature may also be called something like Audio delay or Lip-sync.
     • Use the following suggestion if the sound is distinctly heard before seeing the picture.
       • Turn off any advanced video processing on your TV, such as motion smoothing or noise reduction. These controls are often found in a Video or Picture Settings sub-menu within the Settings menu on your TV.
     • Try the suggestions below if the sound is distinctly heard after seeing the picture.
       • Set your TV's digital audio output to PCM. You can often find this setting in an Audio sub-menu within the Settings menu on your TV.
       • Try turning off Game Mode if the setting exists on your TV.
